FILM-REVERSING MECHANISM.

Specification of Letters Patent. Paten ted Aug. 24, 1909- Applicationfiled August 19, 1908. Serial No. 449,328.

To all whom it may concern:

Be it known that I, Josnrn M. Tnrviss, a subi'ect of the King ofPortugal, residing at Phi adelphia, in the county of Philadelphia andState of Pennsylvania, have invented a certain new and useful FilmReversing Mechanism, of which the following is a specification.

As at present constructed it is necessary after exhibiting a film upon amoving picture machine, to remove the reel containing the filmexhibited, place the same upon a table or other convenient place andrewind said film upon another reel, or in other words, reverse the filmso that it Will'be in proper position to again exhibit. This rewindingor reversing operation takes place where the film is unprotected and indanger of being ignited since it is highly combustible. Aside from thisfact, much time is consumed in the rewinding or reversing operation.

The principal object of the present invention is to provide apparatuswhereby a film that has been exhibited may be rewound or reversed by thesame operation of the moving picture machine exhibiting another film.

A further object of the invention is to provide a fire-proof attachmentwherein a reel containing a film may be rewound or reversed.

Other objects of the invention relate to general details of constructionand arrangement of parts as will appear hereinafter.

The invention consists of the improve- 'ments hereinafter described andfinally claimed.

The nature, characteristic features and scope of the invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof and in which:

Figure 1, is a view in side elevation of one type of so-called movingpicture machine having coupled therewith apparatus embodying theinvention. Fig. 2, is a front view of the attachment of the inventionand shown as having its door or cover in 0 en position. Fig. 3, is aview in section taken upon the line 33 of Fig. 2; andFig. 4, is a rearview of the same drawn to a reduced scale.

Referring to the drawings one ty ,e of socalled moving picture machineis ill ustrated wherein there is illustrated a table 1, upon belt 9, asis clearly illustrated in Fig. 1.

which is mounted the lamphouse 2, u per and lower film magazines 3, and4, am the film operating mechanism including the take-up shaft 5, towhich motion is imparted by means of a hand-crank 6. These parts are allwell known in the art and have been described merely for a betterunderstanding of the invention. Upon one end of the takeup shaft 5, andpreferably upon the side of the machine opposite the hand-crank 6, I fixa grooved or other pulley 7, so that motion may be imparted to a similarpulley 8, of my film reversing device by means of a :AS shown in Figs.2, 3, and 4, of the drawings the film reversing apparatus is shown ascomprising a generally rectangular fire-proof box 10, supported at itsrear by means of a frame 11, an provided at its front with a lunged andflanged door or cover 12.

Referring more particularly to Figs. 3, and 4, the frame 11, is shown ascomprising a series of feet 13, provided with apertures 14, whereby theattachment may be suitably fastened in place, said feet extendingupwardly and terminating in a rib 15, which in turn branches at its topinto arms 16. The various parts of the frame 11, may be secured to thebox 10, by means of rivets or other suitable securing devices 17. Boltedor otherwise secured to the frame 11, and adjacent to its upper portionis a bracket 18, which together with said frame constitute a bearing forthe rotatable shaft 19, that carries the pulley 8. This shaft isprevented from endwise movement with respect to the a paratus by meansof collars 20. As clearly illustrated this rotatable shaft 19, extendswithin the box 10, and is rovided with a key 30, and is adapted for t ereception of a reel 21. Also extending within the box 10, is a fixedshaft 22, shown as being secured to the frame 11, by means of a nut 23.A reel 24, is adapted to be carried by this shaft 22, and is kept inalinement with the reel 21, by means of the collar 25. Carried by thedoor 12, are s rings 26, that are adapt ed to press against the reels21, and 24, when the door is in closed position and serve to keep thereels in proper alinement.- In this connection it may be remarked thatthe door or cover 12, is provided with flanged )ortions 27, that serveto prevent sparks or re from entering the box when said cover is inclosed position. The box 10, is provided with catches .28, and the cover12, is provided with hinged latches 29, for codperating with.said'catches to lock the parts together.

In operation a reel 24, containing an exhibited film is removed from thelower magazine 4, and placed upon the fixed shaft 22, within the box 10.and the free end of said film is secured to the reel 21, by means of thespring clip 31. A film to be exhibited is t ien placed in properposition upon the moving picture machine whereupon the operator turnsthe crank 6, thus exhibiting the new film, and by the same operationcausing the pulley 7, to revolve and thus transmit motion by means ofthe belt 9, to the pulley 8, of the box 10, and thus rewind or reversethe exhibited film upon the reel 21, so that it is in proper position tobe inserted within the upper magazine 3, to again be exhibited.

The apparatus above described is simple in construction, eificient inoperation, and saves considerable time and extra expense in rewindingthe films. The box 10, being of fire-proof material recludes thepossibility of the ignition of the lm being rewound, and being separateand apart from the machine may be placed in any convenient position outof the road of the operator and can be readily taken down and moved withthe machine which is an essential feature in machines of this character,that are apt to be moved from place to place.

What I claim is:

1. In combination film moving mechanism, film rewinding apparatuscomprising a driven spindle, an idle spindle, reels for-said spindles, aclosed fire-proof casing located adjacent said mechanism containing saidrewinding apparatus and through which the driven spindle projects, adriving element upon the extended and of said driven spindle, a door insaid casing through which the reels may be placed in position on the sindles and means operatively connectin sai film moving mechanism and thesaid riving element.

2. In combination film moving mechanism, film rewinding apparatuscomprising a driven spindle, an idle spindle, reels for said spindles, aportable fire-proof casing located adjacent said mechanism containingsaid rewinding apparatus and through which said driven spindle projects,a movable flanged cover for said casin a pulley upon the rojected end ofsaid diiven 5 indie, and a elt operatively connecting sai( filmmechanism with the pulley of the driven spindle.

3. In combination film moving mechanism including its complementaltakeup shaft, film rewinding mechanism comprising a driven spindlehaving keyed thereto a reel, an idle spindle having loosely mountedthereon a reel, a closed fire-proof casing located adjacent said filmwinding mechanism containing said rewinding ap aratus and through whichthe driven spind e projects, a

door in said casing through which the reels may be placed in position onthe spindles and means operative y connecting said takeup shaft and thedriven spindle.

4. An apparatus of the class recited comprising a portable stand saidstand comprismg feet terminating in an upwardly extending rib, a bracketfixed to the upper portion of said rib, a fire-proof casing carried bysaid rib, a flanged cover for said casing, a driven and an idle spindlewithin said casing the driven spindle being projected through saidcasing, rib and bracket, reels for said spindles and a driving pulleyfor the extended end of said spindle.

5. Apparatus of the class recited comprising a stand, a closed casecarried thereby, a movable flanged cover for said case, reel receivingmembers within the case of which one is fixed and the other rotatable,means for rotatin the last mentioned member and means for Iieeping saidreels in alinement.

6. Apparatus of the class recited comprising a stand, a fire-proofcasing mounted thereon, a flanged cover for said casing, reel receivingmembers Within the casing one of which is fixed and the other rotatable,means for operating/the last mentioned member and means for locking thecover with respect to the casing.

In testimony whereof I have hereunto signed my name.
